AWS Certified Big Data – Specialty — Question 34

A company needs a churn prevention model to predict which customers will NOT renew their yearly subscription to the companys service. The company plans to provide these customers with a promotional offer. A binary classification model that uses Amazon Machine Learning is required.
On which basis should this binary classification model be built?

Answer options

• A. User profiles (age, gender, income, occupation)
• B. Last user session
• C. Each user time series events in the past 3 months
• D. Quarterly results

Correct answer: C

Explanation

The correct answer is C because analyzing each user's time series events in the past 3 months provides crucial insights into their behavior and engagement, allowing for a more accurate prediction of churn. Options A, B, and D do not capture the temporal patterns necessary to effectively model churn risk.
